宝骏530 1.5T 前氧传感器23528221 总长415mm 专用设计

When your Baojun 530 1.5T shows check engine light, rough idle, abnormal fuel consumption, or weak acceleration, the upstream oxygen sensor aging or failure may be the cause. This sensor monitors exhaust oxygen content and feeds ECU to precisely control air-fuel ratio for efficient combustion. Brand KLP; OEM 23528221; total length 415mm; designed for Baojun 530 1.5T; compatible with OEM standards. Use dedicated socket to remove old part carefully to avoid thread damage; ensure new sensor harness is securely connected without bending or contact with exhaust.
